Title: External combustion engine.
Inventor: ASKAM EDGAR STANLEY
IPC: F01K11/04
Filed: 1993-05-10
Abstract: The engine comprises a sealed casing 12 mounted on a shaft 4 and containing an auger-like power section 9, having pressure-tight webs 18, each carrying a jet 17. A reservoir 6 is supported by bearings 15 on the shaft and a scoop 3 is provided to collect condensate from the inner wall of the casing and feed it to the reservoir. Fluid flows from the reservoir to a central bore in the shaft 4 which is internally screw-threaded to force fluid towards an impeller 11. Fluid thrown from the impeller is vaporised by heat from a burner 13, the vapour passes through the power section and is condensed by extraction of heat via a water jacket 2. Condensed fluid is thrown by centrifugal force to the wall of the casing 12 for collection by the swop 3 and subsequent re-cycling. The working fluid may be trichlorotrifluroethane, and the burner 13 may produce carbon-mon-oxide free exhaust. <IMAGE>

Patent GB-2300499-A (GB)
Title: One-chip CPU with memory protection
Inventor: SATO OSAMU
IPC: G06F21/79
Filed: 1996-04-30
Abstract: A one-chip CPU (Central Processing Unit) has a program counter, a built-in inside memory, a gate circuit, a decode circuit, and an inside bus. The program counter is connected to the inside bus and built-in memory while the memory is connected to the decode circuit via the gate circuit. Further, the program counter is connected to the gate circuit. When the logical value of the program counter is representative of the built-in memory, an inhibit signal is not fed to the gate circuit. However, when the logical level is representative of an outside memory, the inhibit signal is fed to the gate circuit so as to close it. As a result, the gate circuit obstructs the flow of data from the built-in memory. This protects data stored in the built-in memory from illicit accesses based on a program stored in the outside memory.

Title: Liquid crystal display device and production method thereof
Inventor: TAGUCHI NOBORU
IPC: H01L21/84
Filed: 1996-02-23
Abstract: A liquid crystal display device using a thin-film diode or a thin-film transistor as a switching device. A method of producing the device comprises the steps of forming a protective film on the entire surface of a substrate on which switching devices and signal electrodes or scanning electrodes are formed, forming openings in the protective film between the electrodes, and etching away the remaining portion of each electrode material inside the openings. For example, the protective film is disposed on the entire surface of the substrate (1) on which a back-to-back connection of two thin-film diodes (11 and 12) is provided corresponding to each pixel electrode, and opening portions (36) having openings (36c, 36d and 36e) are disposed between the pixel electrodes (6), between the signal electrode (13) and the pixel electrode (6) and between the signal electrodes (13), respectively. The remaining portion of the electrode material inside the opening (36) is removed by etching. Because short-circuits between the electrodes as indicated by (21, 32 and 34) can be eliminated, surface defects can be drastically reduced, display quality as well as production yield can be improved.

Title: Output voltage stabilizing circuit of a power factor correction circuit
Inventor: KIM SANG YEAL
IPC: H02M1/42
Filed: 1997-09-04
Abstract: An output voltage of a power factor correction circuit is initially stabilized by controlling an on-off timing of a reference oscillating waveform which varies in response to an error voltage in accordance with a charge/discharge voltage outputted from a soil start circuit 60. The stabilizing circuit includes a flyback transformer 40 connected to a secondary winding of output transformer 30 for applying a high voltage and outputting a sync signal, a first control driver 50 for outputting a control signal to switched mode power supply transformer 30, soft start circuit 60 for charging or discharging capacitor C2 according to an output of the transformer 30, a switching section 70 for controlling the charging or discharging of the soft start circuit in response to the sync signal, an error amplifier 80 for amplifying the output voltage of the power factor correction circuit 20, comparing section 90 for comparing an output voltage of the amplifier 80 with the initial output voltage of the power factor correction circuit, and a second control driver 100 for controlling a duty ratio to stabilize the initial output voltage of the power factor correction circuit. During start-up, switching transistor TR1 is off, but after a preset time, FBT 40 produces the sync signal to turn transistor TR1 on, reducing the voltage across resistor R5 and increasing the waveform on-time, so as to stabilize the output voltage of the power factor correction circuit 20 at a normal level.
Patent GB-2322089-A (GB)
Title: Workpiece support device
Inventor: WAYMAN JOHN CHARLES
IPC: B23Q1/03
Filed: 1998-02-09
Abstract: A workpiece support device comprises an array of rods (2) in columns and rows with free ends of the rods forming a support surface, in which support surface recesses can be created by selectively retracting individual ones of the rods (2). Each rod (2) is coupled to a respective piston (3) within a respective cylinder (1) and each cylinder (1) in a row has an upper connection (4) for medium pressure and a lower connection (7) for high pressure. Each cylinder in a column has a middle connection (8) for low pressure. A trigger piston (5) is provided in a cylinder (6) below the piston (3). The rod (2) can be caused to extend from the cylinder (1) by applying low pressure to the connection (8) to press the trigger piston (5) downwardly to close the high pressure connection (7). Such low pressure passes around the lip of a lip seal 24 on the trigger piston 5 and through a connection 28 pressurises the underside of the piston 3 to raise the piston 3 and release it from pressing the trigger piston 5 downwardly. Subsequently pressurising the connections (4) and (7) causes the differential pressure to force the piston (3) upwardly. However by sequencing the application of pressure to the connections (4, 7 and 8) the rod (2) can be locked in the retracted position. Medium pressure applied to the connection (4) presses the piston (3) downwardly to abut the trigger piston (5) and hold it in a depressed condition in which it will remain even after pressure is restored to the high pressure connection (7).

Title: Hydraulic brake system
Inventor: THOMAS RICHARD PAUL
IPC: F16D57/06
Filed: 1998-06-15
Abstract: The Hydraulic Brake system operates by the way the front wheel rotates around the hydraulic pump (B1) Pumping fluid to the calliper (A) and back to the pump. To slow the wheel and pump you put your foot on the brake which in turn pushes brake fluid down the brake pipe (A3) to the calliper (A) moving a piston forward to reduce the flow of hydraulic fluid around the system. The back pressure slows the hydraulic pump down, which is bolted to the wheel (B5) so as to reduce the speed of the wheel. The system will eliminate pads and shoes so not to create friction.

Title: Random walk hydraulic modelling of fractured petroleum reservoirs
Inventor: NOETINGER BENOIT
IPC: G01V1/28
Filed: 1998-07-03
Abstract: A method of determining, from a 3D image, the values of hydraulic parameters such as large-scale equivalent permeability, the permeability of blocks and the exchange coefficient alpha between matrix and cracks of a porous fractured medium such as a geological formation. The method essentially consists in breaking down the medium by means of a grid and rapidly and approximately solving in this medium equations which model the diffusion of fluids in the medium, determining the variation over time of a large-scale transfer function (f(t), f(s)) characterising the flows of fluid from the matrix to the cracks by simulating the movement of particles following continuous-time random walks on said grid and appropriately processing a function of state (#(#)) indicative of their presence either in the matrix or in a crack. Application to large-scale modelling of fractured petroleum reservoirs, enabling the interpretation of well tests, is also described.

Title: Overflow fitting for a syphon-discharge toilet flushing system
Inventor: HATTON MARTYN JOHN CHARLES
IPC: E03D1/08
Filed: 1998-10-03
Abstract: A toilet flushing system comprises a syphon (16) for location in a cistern (12) and including an overflow pipe (22) so that excess water flows out of the cistern through the overflow pipe when the water rises to a level above the normal static level (15) of water in the cistern, and including means (26) for breaking the syphon if the overflow continues for more than a predetermined period. Preferably the means (26) for breaking the syphon comprises means (23) defining a passage (25) connecting an intermediate part of the syphon with the interior of the cistern, substantially at the level at which water starts to overflow through the overflow pipe, and a closure member (26) of a material degradable in water normally closing the passage (25), such that when water flows through the overflow pipe, the closure member is contacted by water and degrades in said predetermined time to open the passage (25) and air break the syphon. The invention also extends to a method of adapting a syphon flushing system in a toilet, which comprises connecting a pipe containing a closure member (26) which is biodegradable in water within a predetermined time, into an intermediate part of the down arm of a syphon tube.

Title: Drilling apparatus
Inventor: EATON M R
IPC: E21B47/12
Filed: 1998-11-20
Abstract: A drilling rig 10 supports a drill string 11 within a borehole 12. An acoustic receiver 14 is associated with a drill bit 13 connected to the end of the drill string 11. An acoustic source 16, such as an airgun, is located at the earth's surface 17 some distance from the rig 10. In operation, the acoustic source 16 is controlled to transmit an acoustic pulse downwards into the rock formations surrounding the borehole 12. The acoustic energy travelling on a path 18 reaches the rock in contact with the drill bit 13 which is thereby detected by the acoustic receiver 14. Boundaries 20 and 23 in the rock formations are detected and their positions determined by receiving signals from the source 16 after reflection by the boundaries 20 and 23. Time-depth check-shots may be obtained by timing acoustic propagation along either path 18 or path 27. A Vertical Seismic Profile can be obtained by performing measurements with the drill bit 13 at different depths in the borehole.
